An analytical chemist weighs out of an unknown triprotic acid into a volumetric flask and dilutes to the mark with distilled water. she then titrates this solution with solution. when the titration reaches the equivalence point, the chemist finds she has added of solution. calculate the molar mass of the unknown acid. be sure your answer has the correct number of significant digits.

your answers are a,b,,e and f

ans is no, the data set cannot be plotted as a single circle graph

answer: semi-infinite solid initially at a uniform temperature of 400 ◦c is cooled at its surface by convection. the cooling fluid at a constant temperature of 200 ◦c has a convective coefficient (ha) of 250 w/m2.k. the physical properties of the solid: k = 20 w/m.k and α = 4 * 10-5  m2/s. using δx = 0.04 m and δt = 10 s. write the finite difference equations describing the transient heat transfer of the first five δx and the temperature profile after 30 s.
